Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489474, here are decompositions:

11 + 31489463 = 31489474
41 + 31489433 = 31489474
47 + 31489427 = 31489474
83 + 31489391 = 31489474
227 + 31489247 = 31489474
257 + 31489217 = 31489474
281 + 31489193 = 31489474
293 + 31489181 = 31489474

Showing the first eight; more decompositions exist.
